PIPE-HA GER.

To all whom it may concern:

Be it known that I, LOUIS A. Honnn, a citizen of the United States,residing at the city of St. Louis, Missouri, have invented a certain newand useful PipeHanger, of which the following is such a full, clear, andexact description as will enable any one skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification.

The object of the present invention is to provide apipe hanger in whichthe pipe'is secured without the use of screws or nuts and to this end Iprovide the hanger with an integral gripping member which is preferablysprung into engagement with the pipe.

In the accompanying drawings which illustrate one form of pipe hangermade in accordance with my invention, Figure l is an end view; Fig. 2 isa side View; Figs. 3 and 4 are views similar to Figs,-1 and 2 butshowing the hangerin position to be sprung into engagement with thepipe.

Like marks of reference refer to similar parts in the several views inthe drawings.

"10 is the body of the hanger. A step portion 11 of the hanger 10 isformed at, right angles to the body 10 and is adapted to be secured toany suitable support, as for instance, the ceiling 12 by means of screws13 passing through openings 1% in the said part 11. Formed integral withthe body 10 of the hanger is a gripping or clamping member 15 which isspiral in form, as best shown in Figs. 2 and 4. This spiral grippingmember 15 is made to slightly more than completely surround thecircumference of the pipe, as is indicated by the end of the said memberextending past the horizontal line A-A-through the center of the pipe atright angles to the body 10, as illustrated in Fig. l. The body 10 andgripping member 15 may be provided with a strengthening rib 16, asillustrated in the drawings. 17 represents the pipe which is engaged. bythe gripping member 15. Inasmuch as the Specification of Letters Patent.

gripping'member 15 more than completely surrounds the pipe it will benecessary to spring the said gripping member into engagement with thepipe. This is done by bringing the parts into the position shown inFigs. 3 and i and thus 10 of the hanger into a By making the hanger fitthe pipe snugly it will grip the pipe firmly so as to hold it not onlyagainst pivotal movement in any direction but also against longitudinalmovement. The pipe, however, is not held sufliciently tight to preventlongitudinal movement-due to expansion and contraction of the pipe.Furthermore, such movement does not tend in any way to lessen the holdon the hanger of the pipe. To remove the hanger from the pipe the abovementioned process is simply reversed.

The convolution of the helical extension is of such a pitch that thedistance between the extremity of the gripping memberand the shank ofthe hunger is such that the pipe may bepositioned therein, after whichthe shank, which is substantially rigid, is moved in a directionparallel to the pipe to spring the yielding end of the helical extensionthereover and properly position the end of the shank for attachment toits sup- )ort.

1 What I claim as IIIy-IIIVGIIiJlOII is:

As an article of manufacture, a pipe hanger formed of a strip having ashank portion and a pipe engaging portion, the pipe engaging portionextending helically to one side of the shank portion and adapted toembrace a pipe, said pipe engaging portion being provided [with aclamping end vertical position.

which is adapted to be sprung onto the pipe. to hold it againstmovement.

forcing. the body In testimony whereof, I have hereunto set my hand andafiixed my sealgin the presence of the two subscribing witnesses.
